There was never anything to fear from Saddam. Any supposed WMD that he might have patched together would not amount to anything. It was used as a pretext for Bush's invasion, pure and simple. Even Colin Powell admits he was had.

If there were any usable materials in Iraq that could have fashioned WMD's, they were
supplied by Bush Senior and the U.S. military so Saddam could win against Iran.
But UNSCOM did its job. Any attempt to manufacture a yellow cake of WMD's in Iraq
is risible.

Fear is the biggest motivator in the attempt to manufacture a straw-boogey-man.
